About The Use Of Magnetic Powder Brakes

The magnetic powder brake manufacturer transmits the torque according to the electromagnetic principle and the magnetic powder. It has a linear relationship between the excitation current and the transmission torque. It can transmit a certain torque regardless of the slip, and the response speed is fast and the structure is simple. The advantage is a multi-purpose, superior performance automatic control component. It is widely used in brake, loading and unwinding tension control in various systems for various purposes.

The base magnetic powder brake is an excellent automatic control element. The base type magnetic powder brake has the advantages of simple structure and control, high speed response, high control precision, wide torque control range, low power consumption, low running noise, durability, etc. It can be used for various mechanical brakes (brakes). It can also be used for load control of various systems for tension control and torque measurement. The base type magnetic powder brake is widely used in rubber, packaging machine, plastic processing, coating machine, printing, paper making, wire and cable unwinding, winding tension control, etc. It can improve the overall quality and greatly reduce the occurrence of defective products. Modern industrial production machinery is a commonly used transmission equipment.

The single-row shaft-type magnetic powder brake is an indispensable transmission device for unwinding and tension control systems of long-sized materials such as paper, electric wires and various films. It transmits torque through magnetic powder and can be freely controlled and adjusted by a tension controller. Achieve constant tension. Single-arc-type magnetic powder brake is one of the common transmission equipments in modern industrial machinery. It has the characteristics of speed response, durability, simple structure, energy saving and environmental protection. It is widely used in printing machines and packaging machines in industrial machinery. In the unwinding and tension control systems of textile machines, wire and cable, printing and dyeing, rubber and other industrial machinery.

The selection of the single-row shaft-type magnetic powder brake is generally selected according to the large torque and slip power that need to be transmitted according to the rotational speed. Note that the actual slip power cannot be greater than the allowable slip power of the magnetic powder clutch.

Tension control system requirements for the use of single-outlet stand-type magnetic powder brakes are as follows:

1. When selecting the type, consider whether the torque can meet the requirements of the tension control system.

2. The heat generated during operation should not exceed the allowable continuous slip power of the model used.

3. The selection is based on the comprehensive mechanical support. The automatic tension controller determines how much torque is required to reach the load, and whether the installation method and space meet the requirements.

The recommendations for the above situation of the magnetic powder brake are as follows:

1. Before the official operation or after the device is moved, it must be operated evenly to be officially operated. In this way, smooth torque can be generated. The uniform operation mode is as follows: In the non-excited state, the drive side is rotated as fast as possible (after 1800 rpm) for about 1 minute, and the excitation current is set at the rated 1/4-1/5, one. On the side of the slewing drive side, on the one hand, open in 5 seconds, close in 10 seconds, and excite the magnet for about 20 times.

2. When choosing to purchase the magnetic powder clutch/magnetic powder brake, it is better to choose a product with guaranteed quality.

 The magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque. The magnetic powder brake can transmit a certain torque regardless of the slip. It has fast response, simple structure, no pollution, no noise, no impact vibration and energy saving. Etc. It is a multi-purpose, high-performance automatic control component.

There are several cases in which the magnetic powder brake is stuck:

1. The magnetic powder filled between the two groups of units is scattered on one side during transportation or the installation time is too long, and the magnetization is not caused by the excitation before starting the machine.

2. Due to the low manufacturing precision of the product, the concentricity of the rotor is not enough, resulting in uneven output torque or stuck.

3. In the process of production, the magnetic powder is excessively sealed.

4, caused by the use of inferior magnetic powder.

The recommendations for the above situation of the magnetic powder brake are as follows:

1. Before the official operation or after the device moves, the micro magnetic powder brake must be evenly operated to be officially operated. In this way, smooth torque can be generated. The uniform operation mode is as follows: In the non-excited state, the drive side is rotated as fast as possible (after 1800 rpm) for about 1 minute, and the excitation current is set at the rated 1/4-1/5, one. On the side of the slewing drive side, on the one hand, open in 5 seconds, close in 10 seconds, and excite the magnet for about 20 times.

2. When choosing to purchase the magnetic powder clutch/magnetic powder brake, it is better to choose a product with guaranteed quality.
